Good cost-benefit relationship, for the smart-trainers class. The resistance works fine in ERG mode via Zwift; other apps did not work well for me. Good product overall.
I had been a happy user of the SuperMagneto Pro for 4 years. This new model, Magnos trainer, isn't as sturdy as the Pro series; its materials are more fragile and feel cheap in comparison. Besides, the "road feeling" of the Pro is superior, specially in high power, low speeds. It is also much noisier than the Pro, specially at higher speeds (hint: I found that if you select lighter gears, the trainer will adapt the resistance likewise, but the the rear wheel will spin at lower RPM and there will be much less noise).

The Magnus excels at simulating cycling when conditions, weather, time, or other priorities don't allow for getting outside. The accompanying software allows for programmed workouts that can emphasize strength, cardio endurance, increasing vo2, increasing LT, etc. Or it can be used to simulate a particular route or race. The many options keep indoor training from getting monotonous. The wheel on trainer is easy to set-up, use, calibrate and ride. I look forward to time on the trainer as one of the best workouts I can get in small windows of time.

Product was easy to assemble. I bought this specifically for Zwift and while it connected to my phone and PC right away on the Cycleops software. Zwift using the phone BLE proxy is not the best way to connect. I'd give 5 stars if it came with an ANT+ dongle.

This thing is pretty responsive for a trainer. I use it with zwift and it gives you a killer work out. If the weather is bad out or I don't want to load my bike up in the morning I just pick a course and ride on this.

I bought this at the local bike store after reviewing various products. I had a cycle ops fluid trainer before, and threw it away after excessive leaking. The hardware was easy to setup, maybe 20min total.
But i could not figure out how to sync it with my laptop. I think it is a bluetooth issue, but laptop doesnt have Bluetooth. Suspect there is some plug in adapter i need, but haven't been able to find exactly what I need.
I hope I can figure it out, because the video is awesome, projected onto large wall.

I've been using the Magnus for 2 months now and it has worked flawlessly. Easily connects to my iPad for riding on Zwift and other services. One firmware update since I have purchased it after disconnecting halfway through, the second time it loaded with no issues. The tension knob is a very nice feature. The way it has been designed ensures you will have the same exact pressure on your tire (providing you keep the same air pressure of course) every time you install your bike.

I upgraded from the Fluid2 to the Magnus (partly because Performance had a great deal on a pre-order). It works really well for intervals, once you figure out some of it's idiosyncrasies, especially when using it with TrainerRoad (which is what I use it for exclusively right now).
I follow the tension and turn the knob until it clicks. Works fine for me with a trainer-specific tire (on a trainer-specific spare wheel).
There is no documentation describing when you should calibrate the trainer. When you start? After a warm up (the trainer does not get hot like the Fluid2 did)? Every time you use it? Use the CVT calibration or the new PowerTab spin down calibration? There's nothing describing how to get the best, most consistent results.
Second, I discovered you have to disable TrainerRoad's Power Match. When it was on, it would sometimes get confused and calculate a big negative offset, so you were locked in 100W below target. This isn't an issue with the Magnus, but with the integration of the Magnus with TR. I report this for others to learn, as this alone had me considering returning the Magnus for a KICKR SNAP.
I have to agree with another reviewer that it could use a heavier flywheel. Not for road feel, as it doesn't matter how closely a trainer might mimic the road, I still know I'm on a trainer. I think this would help smooth out the power readings a bit more.
I will say that now using an ERG versus a Fluid is a LOT more effective. It's paid off huge in improving my power and endurance!
I'm hopeful I can get the rest of these niggling issues sorted out soon.
